We are several institutions in Finland working together to ETL our databases into the OMOP-CDM.
We are creating (and mapping) local vocabularies that eventually we would like to add to Athena.
However, it may take some time to arrive to consensus on these vocabularies, and we would like to use them already to compare our databases not only at the concept_id level but also at the source_concept_id level.
Is it, for example, possible to reserve an unused range of concept_ids ? this way when our vocabs are ready we can add them to Athena without having to change them/
or how do you handel this situations, im sure we are not the first ones with this question
